To satisfy the demand for flexibility plus ever-increasing data rates, cooling capacities and power consumption, Pentair has developed the Schroff AdvancedTCA ECO Modular System. Designed with user-friendliness in mind, this 14U AdvancedTCA system offers 14 slots and is based on a modular concept with a cost-optimized scope of features. All features can be upgraded or minimized as required and the cooling and power supply can be easily adapted to suit.

A removable fan tray provides optimal cooling of the ECO modular system, featuring six or eight standard fans and delivering a cooling capacity of 250 W or 450 W per blade respectively. Alternatively, six higher-output fans may be used together to provide cooling of over 500 W per blade. With these modular fan drawer options, system cooling capacity and costs can be designed with flexibility. The ECO modular fan tray is fitted below the board cage and connected directly to the backplane.

The Telco alarm panel and the two RJ45 connectors for the shelf manager ports are positioned on the front panel of the fan tray. No separate alarm module is required. With the fan tray in autonomous mode, the system can also be operated without a shelf manager. In this case, the fan controller monitors the air inlet and air outlet temperatures and sets the fan speed accordingly. The modular concept of the PEM supports 250 or 500 W per slot and a power supply unit with or without redundancy. To achieve this, Pentair developed a PEM board that includes input filtering and two 50 A fuses.

The Schroff ECO Modular System is available with two backplane options: a Dual Star version and a Dual-Dual Star version. Both backplanes satisfy the requirements of IEEE 40GBase KR4, i.e. Ethernet with a data transfer rate of 10 Gb/s per port and four ports per channel. This gives a total of 40 Gb/s between blade and switch (40G backplane). In the case of a Dual-Dual Star backplane, four switches are used. Data can thus be sent via two switches in redundancy mode, resulting in 80 Gb/s overall. If the switches are configured for 3+1 redundancy, a data rate of 120 Gb/s can be achieved between the blades. The IPMB management bus on both backplanes is bussed.
